Abstract: Disclosed is a method for preparing graphene-based carbon fibers at room temperature. The fibers have excellent properties such as high strength, a high modulus, high toughness, high electrical conductivity and high thermal conductivity. The method is as follows: embedding an apparatus for fluid liquid crystal partitioning in a spinneret, regulating a graphene oxide spinning solution via partitioning, and then dividing same into fine microfiber structures, and entering a solidification bath. Multi-stage plasticizing and stretching is performed on the solidified graphene oxide fibers until the limit is reached. The stretched fibers are then immediately reduced by means of a prepared high-efficiency reduction bath under tensile stress. The graphene-based carbon fibers which have high strength, a high modulus, high toughness, high electrical conductivity, and high thermal conductivity are assembled at room temperature. The present invention sets forth a method for preparing graphene-based carbon fibers at room temperature. Graphene oxide is used instead of a polymer as a precursor of carbon fibers. The preparation efficiency is high, no heat treatment is required, the cost is extremely low, and the method conserves energy and is environmentally friendly.
